Description

Comprehensive treatment method of kitchen cleaning wastewater and kitchen waste

technical field

The invention relates to the technical field of domestic waste treatment; a comprehensive treatment system and treatment method for kitchen cleaning wastewater and kitchen waste.

Background technique

1. Urban problems

(1) Urban water source is in a hurry: urban development has led to an increase in urban water consumption year by year. The national ecological environment construction has made the green area increase year by year, and the green water consumption has surged. The urban water source needs to be comprehensively considered from the aspects of water conservation, utilization of reclaimed water, and rainwater interception (sponge city). At present, the reclaimed water mainly comes from the advanced treatment water of the urban sewage plant.

(2) Kitchen waste: The amount of urban domestic waste has surged, and according to the principle of waste classification, it is divided into four categories: kitchen waste, recyclable waste, hazardous waste, and other waste. Kitchen waste is non-recyclable. The disposal methods of kitchen waste are mainly sent to landfill, composting and incineration, which has become an urgent urban problem to be solved.

(3) The demand for organic fertilizers has surged: With the construction of the national ecological environment, the green area has become larger and larger, resulting in a surge in the amount of organic fertilizers. Therefore, the production and utilization of organic fertilizers bring about environmental problems, raw material problems, energy problems, and transportation problems. exacerbated.

2. Household garbage disposal

At present, the technology of household waste disposer is a pure pulverization technology, and its purpose is to discharge some kitchen waste into the urban drainage system through the indoor kitchen drain pipe. After its use, there are the following main problems that are not suitable for widespread use: (1) the operation load and electricity load of the urban sewage plant are increased, and the cost of sewage treatment is increased; (2) the urban drainage pipe network is blocked and the urban sewage plant (3) The amount of kitchen waste treated by household waste disposers is less than 10% of the generated volume, which cannot fundamentally solve the problem of kitchen waste disposal. (4) Most domestic sewage plants basically do not have the ability to accept domestic waste, (5) increase the water consumption of urban tap water, and (6) are expensive.

Change the current large-scale disposal of kitchen waste into a household treatment and comprehensive utilization model, and turn kitchen waste into recyclable garbage, saving time and effort, not occupying land, and causing no pollution, and ending the sending of kitchen waste into garbage dumps. The mode of treatment in landfills, waste incineration plants and kitchen waste treatment plants has changed the ecological environment.

The urban kitchen waste disposal mode of the present invention is that the kitchen waste generating points are composted indoors and then directly transported for comprehensive utilization, which saves the collection, transportation and composting links of urban kitchen waste, and can make all the kitchen waste generated in the city. Composting and utilizing the remaining garbage will bring huge economic and social benefits to the society.

The present invention makes up for the blank of the prior art:

(1) Changed the existing urban kitchen waste disposal mode

The amount of urban kitchen waste is huge (about 0.5kg per person per day). At present, the disposal mode of urban kitchen waste is as non-recyclable garbage, which is collected through the urban environmental sanitation facility engineering system and transported to landfills or landfills. After incineration in waste incineration plants and the collection of kitchen waste generated by the catering industry, some are sent to waste composting plants for composting and comprehensive utilization, and some are sent to landfills for landfill. Therefore, some urban kitchen wastes are composted and utilized, and have The transportation of kitchen waste is time-consuming, labor-intensive, and the working environment is harsh. When landfilling, incinerating and composting, the equipment occupies a large area, the disposal equipment is expensive, the disposal cost is high, and the pollution is high.

(2) The function of the existing household waste disposer has been changed

The function of the existing household garbage disposer is to use a large amount of tap water to assist in pulverizing the kitchen waste, and push the pulverized kitchen waste to discharge into the indoor drainage pipe. The function of the present invention is to use pre-collected kitchen cleaning waste water to assist the crushing, heating and fermentation of kitchen waste, and turn it into organic fertilizer within a specified time (the same day).

(3) Changed the structure of the existing household waste disposer

At present, the existing household waste disposer is a single crushing device, and the present invention is a combined device with a fermentation process, which saves water and electricity, and does not generate pollutants. The manufacturing cost of the garbage disposer is reduced, the disadvantage that the existing household garbage disposer cannot be widely used is solved, and the utility model has extensive promotion value.

(4) Changed the existing fermentation technology of kitchen waste composting

The current kitchen waste composting technology belongs to large-scale composting technology. Fermentation is carried out by controlling the following parameters: particle size, special microbial inoculum, C/N, ventilation rate (aerobic composting), gas production (anaerobic composting), organic matter Water content, temperature, etc., the equipment runs continuously (4h ~ 24h or longer). The kitchen waste composting technology of the present invention belongs to the household composting technology, which is to pulverize the kitchen waste in the solid form, put it into the collection bucket in the liquid form and anaerobic stand for fermentation, and the fermentation time is the time that the collection bucket is stored at home. Can be long or short (>1h). Considering that the fermented material is different for each meal, in order to ensure the complete fermentation of kitchen waste, it can be stipulated that it can be placed in the outdoor collection equipment after standing for 4 hours. The time from when organic fertilizer is stored in outdoor equipment until it is comprehensively utilized is also the time for secondary fermentation. The present invention performs fermentation by controlling the following parameters of small household equipment: particle size, water addition, anaerobicity, temperature, etc., no additional microbial inoculum, C/N control, no need to deliberately control the fermentation time, only need to control the collection The storage time of the bucket in the home and the storage time of the outdoor collection bucket can be enough.

(5) Self-contained system

The invention includes indoor and outdoor equipment, and forms a comprehensive treatment system for kitchen cleaning wastewater, kitchen waste and an urban reclaimed water system. It is the organic integration point of urban drainage system, urban environmental sanitation engineering system, sponge city, urban reclaimed water system, urban greening system and urban overall planning. Every household uses indoor equipment to turn all the kitchen waste generated from each meal into organic fertilizer to nourish the soil, and turn the non-recyclable kitchen waste that is harmful to the urban environment into recyclable garbage, which can be cleaned on the same day as daily production. At the same time, the water in kitchen cleaning wastewater and kitchen waste is converted into low-concentration liquid organic fertilizer containing nutrients required by plants, which can be used as urban reclaimed water source and directly used for greening irrigation. Through outdoor equipment, the solid and liquid organic fertilizer mixtures produced by households in the community are collected and separated from solid and liquid. After the solid-liquid separation of the organic fertilizer, on the one hand, the transportation weight of the solid organic fertilizer is reduced, and on the other hand, the collected liquid organic fertilizer is collected and stored to become the urban regeneration water source for urban greening. The whole system is a closed system, in a negative pressure state, and no pollutants are produced.
